Degenerate Integro-Differential Equations of Convolution Type in Banach Spaces

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
We consider an integro-differential equation in convolutions of a special kind in Banach spaces with the Fredholm operator in the main part. The article concerns with the problem of unique solvability of the Cauchy-problem for this equation in the class ...

Adiabatic Fredholm Theory

open access: yes
We develop a robust functional analytic framework for adiabatic limits. This framework consist of a notion of adiabatic Fredholm family, several possible regularity properties, and an explicit construction that provides finite dimensional reductions that fit into all common regularization theories.

Feynman propagators and Hadamard states from scattering data for the Klein-Gordon equation on asymptotically Minkowski spacetimes

open access: yes, 2016
We consider the massive Klein-Gordon equation on a class of asymptotically static spacetimes. We prove the existence and Hadamard property of the in and out states constructed by scattering theory methods.

A class of retarded Volterra-Fredholm type integral inequalities on time scales and their applications

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we study some new retarded Volterra-Fredholm type integral inequalities on time scales, which provide explicit bounds on unknown functions.

Distributions of Quadratic Functionals of the Fractional Brownian Motion Based on a Martingale Approximation [PDF]

open access: yes
We discuss some computational problems associated with distributions of statistics arising from the fractional Brownian motion (fBm). In particular, we deal with (ratios of) its quadratic functionals.

Semi-Fredholm theory on Hilbert $C^{*}$ -modules [PDF]

open access: yesBanach Journal of Mathematical Analysis, 2019
In this paper we establish the semi-Fredholm theory on Hilbert C*-modules as a continuation of Fredholm theory on Hilbert C*-modules established by Mishchenko and Fomenko. We give a definition of a semi-Fredholm operator on Hilbert C*-module and prove that these semi-Fredholm operators are those that are one-sided invertible modulo compact operators ...

On the solvability of boundary value problem for mixed-type equation with a singular coefficient

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
In this paper we study a problem with conditions on the inner characteristic and on some parts of the degeneration line for mixed type equation with singular coefficient in unbounded domain.
